To oli whom fit may concern:

lie it known that we, ORANGE O. Omas and Josnrn llorKiNsors, citizens of the United States, residing at Dayton, in the countyof Montgomeryand Stateof Ohio, have invented certain new and useful improvements in (.iomputing-Scales, of which t he following is a specitieation.

Our invention relates to price scales, and particularly the production of a counter or platfo.l n scale having the capacity to quickly and readily indicate the money alue of merchandise placed upon the goods-receiver or platform at different prices per unit,

The object of the invention is to provide a scale of the type mentioned with an indicator movable angularly in a vertical plane to indicate beth fractional values and fractional weights.

The invention contemplatesthe employment of a counter-scale of the platform type, comprising a system of levens connected with a weighing beam graduated in pounds and ounces and equipped with a movable poise and additional weights when required, with a price and value indicating mechanism controlled and/operated by theimovement of the platform levers, and an indicator movable angularly to indicate value at different rates, a differential counter-balancing device being introduced to resist the movement in proportion to th e weight of the merchandise boing weighed.

The invention consists generally in a platform scale combined with a differential counter-balancing mechanism operating to control an indicator for indicating values when the scale is over-loaded or loaded beyond the point balanced by the weights or poiseupon the weighing beam, the indicator and differential counterbalancing mechanism being also adapted to operate independent of the weighing beam and its weights l' when the same is'balanced at zerd. I

With the above primary and other incidental objects in view, as `will appear from the speciiication, the iuvention'consists in certain novel details of construction l and combinations and arrangements of parts,`as hereinafter described und set forth in the claims. ,y I

Referring to the drawings, Figure. l. is a perspective.,v View of the assembled scale embodying our invention. l

Fig. 2 is a front elevation of the scale with portions of the main frame and the platform removed, Fig. 3 is a detail view showing one of the platform levers and the connection therewith of the two steelyard hooks hereinafter mentioned. l

Referring by letter to the drawings, the main frame comprises a base portion, a, an upright frame portion, alA` adjacent to one edge of said base, and a housing, a, surmoun'tng the frame portion, al, and containing the value chart and indicator. Within the base portion, a, is located a system of levers, one of which is shown at b l 'gfxids-receivcr or platform, b.

(Fig. 3) and upon which is supported the goodareceivor or platform, bl. Fulcrumed upon a suitablel beam stand, b2, located upon the frame portionr a, is a. weighing beam, b3, connected by a steel yard hook, I, with the platform beam, The leverage proportion of the weighing beam, b2, is such that a movable poise, b5, is adapted to counterbalance a considerable weight upon the goods-receiver or platform, b1. lhe steel yard hook, b4, in divided into an upper and lower portion connected by a turn-buckle, b", within which is connected a plunger, bi, operating within a dash-pot, b", supported upon a suitable bracket, b, within the main frame, al, to obviate undue vibrations of the weighing beam in a well-known manner.

As thus far described, the structure constitutes a platform scale of ordinary type, in which the counter poise weight, 11", on the weighing beam. l1, is adapted to counterbalance a considerably greater load upon the In order to make the scale a price scale, an indicator and differential counter 'balancing mechanism are introduced as follows: The

extremity of the platform lever, f1, is bifurcated as at b9, and engaging therewith isa second steelyard hook, c, which at its upper end engages an intermediate lever, c, 'furcrumod at c`-' in the fratrie portion, a. An indicator carrier or hub, c, is journaled preferably on knifeedged pivots, c, in a Asuitable bracket, c", in the main fratrie. To one side of the carrier, el, is an adjustable counter-weight, c, operating as a pendulum weight to counterbalance the load on the platform of the scale. The indicator arm, c, projects at an angle from the carrierior hub in position to register with graduations 'of weight and value indicating figures on a segmental chart, rt', yin the upper portiouof the fratrie or housing, a2. On the front of the indicator carrier or hub is au adjustable eccentric, c7, to which one end of theflexible connection, e8, is attached, the opposite end of said flexible vconnection supporting a stirrup, c", in which bears the extremity of the intermediate lever, c1. The eccentric, c7, is adjustably mounted on the carrier or Ahub in order that itsleverage may be adjusted, and it is held in position by the arm, el, engaged by two ad- I plemental or additional to the counterbalas-tcc of the movable ioise, b5 or an additional weil'hts wtich ma be attached to the weighing beam, bi. For all goods within the, capacity of the chart and the differential ycounterbalance, the Weighing beam and movable poise need not be used.- The connection between-the goodsa receiver or platform, 111 and indicator, c5, Ais. such .that

any vertical mveinentot the platform is transmitted through the steelyard hook, c, to the intermediate lever, c1, the vmovement being multiplied by said .'lver, c1,- and transmitted through the' fiexible'tonnt'ionpiz, to cause a corresponding oscillatory movement of the vin-l dicator, c, thus indicating upon the segmental chart,

d, the weight and value characters corresponding to the load.sustained4 by the goods receiver or platform o1, in excess' o that sustained by the counterpoise, b, upon the weighing, beam, b3. The total weight sustained by the goeds receiver or platform will eqnalthe indicated v Weight plus the weight sustained by Aand indicated,

'upon the graduated weighing beam,

lt-will be readily seen thatbythe 'construction 'de scribed the Weighing beam, (b3, may be utilized for the purpose o tare; and the counterpoise, b5, shiftedA thereon' to cunteriialance the Weight oi thelrece'ptacle previously placed'upon the platform, b, and theweight and value of the commodity subsequentlyfplaced within the receptacle will bc readily and quickly indi: cated by the. movement of the indicator, c?, and ma be rcadin characters of Weight Vand value from the' seg mental chart, d. l v f v The devicelnay alsor be utilized for ascertaining weights beyond the capacity of the segmental chart.

v For instance, ii the chart is graduated, as in the drawings, to indicate Weight, and value to the extent oi tcn pounds, and it is desired to-wcigh merchandise .of approxiinately seventeen pounds, the merchandise being v placed. upon the goods receiver and the counterpoise,

o, boing shiitcd to thcoxtremc pointion the Weighing' process to which is added they value oi thc remainder' as indicated upon thc segmental chart, which will give the'valuc of thc bull; oi merchandise upon thc goodsrcc'civer. l

From the above description, it is apparent that there yhas been )reduced o WoirhinU scalo iosscssiu man" features oivaflvantagc, and which' obviously is susceptible of modification in its forni, prruiortion, detail construction and arrangement of parts, withoui departing troni-the .principle involved or sacrificing; :my of its advantages.
